Has anyone tried the new-ish Canon 50 TS-E 2.8 on the Fuji GFX? It would have a 40mm equivalent focal length to FF. The published MTF suggests excellent performance and there should be a large image circle for good movements.
This is a good length for vignette style interiors where a good bit of shift is needed and would be a good length for general and landscape use.
With this one available, and the TS-E 24mm II, all I would need from Fuji would be a shift lens in the 30-35 range, preferably around 32/24mm equivalent and that would cover most landscape , interiors and architecture for me.
